nvestigators have said that Routh allegedly stole Kyle’s black Ford pick-up truck and drove to his sister’s home in Midlothian telling her and her husband that he killed the two men.
Later that night, investigators said they found what they think is the murder weapon, a semi-automatic handgun, at Routh’s home in Lancaster.Routh’s sister, Laura Blevins, urged her 25-year-old brother, a former Marine, to turn himself in.
Routh telling his sister he traded his soul for a new truck suggests a possible motive in the crime that so far investigators have not yet pinpointed.

Wasn't it reported that it was after a short police chase that he was captured?
